The relationship between the effective refractive index and pore-ratio of nanoporous polymer film

摘要

In this paper, Lichtennecher method and module system simulation method were synthesized to present a formula giving the relation between the effective refractive index and pore-ratio of the polymer nanoporous film made of PS(polystyrene), PMMA(polymethyl-methacylate) and nano-pore. It can be used to design a nanoporous polymer film whose effective refractive index can be fine-tuned with great precision, which is of great importance and pratical value for the design and manufacture of the high performance nanoporous polymer optical waveguide whose effective refractive index difference between the core and the cladding is perfectly controlled and adjusted.
